M03 5.8G VTX video transmitter from BetaFPV is an ultralight, compact module for FPV whoop drones, combining minimal weight with high technical capabilities. The title indicates power up to 350 mW, making the M03 attractive for long-range flights in conjunction with reliable ExpressLRS 2.4G radio communication. This VTX is specifically designed for models with a motor wheelbase of 65–85 mm and is suitable for mini-whoops and micro drones.

Description and Compatibility

The M03 has special mounting holes for installing a micro canopy, such as BetaFPV C02 and C03, which provides simple camera protection without additional modifications. The camera connector is JST-0.8, compatible with BETAFPV C01, BETAFPV C02, C03, and NewBeeDrone BeeEye cameras. An IPX antenna is pre-installed, so no additional soldering is required, and installation takes only a few minutes.

Key Advantages:

• The M03 is ideal for 65–85 mm whoop drones, adding no unnecessary weight to the structure.
• Adjustable output power allows selecting modes from PIT to 400 mW (PIT/25/100/200/400 mW, V1.1) — the title also states up to 350 mW.
• Extremely lightweight — only 1.1 g (without antenna), preserving the drone's balance and maneuverability.
• The included IPX antenna simplifies installation and allows quick preparation of the drone for flight without soldering.
• Mounting holes and internal unit dimensions are adapted for BETAFPV micro canopies for convenient installation of the camera protection housing.
